  • Publication number: 20240100198
    Abstract: The present invention relates to novel, selective, radiolabelled compound having monoacylglycerol lipase (MGL) affinity which are useful for imaging and quantifying MGL receptor expression, distribution and enzyme occupancy in tissues, using positron-emission tomography (PET). The invention is also directed to compositions comprising such compounds, the use of such compounds and compositions for imaging a tissue, cells or a host, in vitro or in vivo and to precursors of said compounds.

  • Patent number: 11904164
    Abstract: Described herein are apparatuses (e.g., systems and devices) and methods of delivering nanosecond pulsed electrical fields (nsPEF). In particular, these apparatuses and methods may provide enhanced safety and robust operation over even very short (e.g., nanosecond and sub-nanosecond pulses) and high voltage pulsing; these benefits may be accomplished by multi-functional isolation of various subsystems and components of the apparatus, even including the low-voltage, control and command portions of the apparatus with extremely low capacitance, high voltage isolation.

  • Publication number: 20230381514
    Abstract: Described herein are apparatuses and methods for applying high voltage, sub-microsecond (e.g., nanosecond range) pulsed output to a biological material, e.g., tissues, cells, etc., using a high voltage (e.g., MOSFET) gate driver circuit having a high voltage isolation and a low inductance. In particular, described herein are multi-core pulse transformers comprising independent transformer cores arranged in parallel on opposite sides of a substrate. The transformer cores may have coaxial primary and secondary windings. Also describe are pulse generators including multi-core pulse transformers arranged in parallel (e.g., on opposite sides of a PCB) to reduce MOSFET driver gate inductance.
